My fish "Doug" has been moving gravel around in his tank (normal landscaping I thought at first) and I have noticed pink pockets along the bottom of the tank lately. Now I am new to Oscars I'm not sure if it's his poop or if Doug may be a Douglina? Does anyone have pics of the eggs so I know what to look for? I would also assume that they group their eggs together where this material doesn't seem to be concentrated in any particular spot. Any thoughts? (PS he did have some live fish, but now I am keeping him strictly on pink pellet-type food)

I shouldn't worry, if your fish do lay eggs then you will not be mistaken, they will probably lay several hundred on a flat surface, lots of little round eggs that will either be white, or brown depending on whether they are fertilised.
